Product Overview
When field wiring needs a reliable, organized termination point, the ABB TU814V1 Industrial Automation Module delivers. This compact Module Termination Unit (MTU) supports up to 16 I/O channels and two process voltage connections, making it a versatile building block for ABB control systems. Rated for 50 V and 2 A per channel, the TU814V1 simplifies wiring while maintaining signal integrity.
The TU814V1 features three rows of crimp snap-in connectors for field signals and process power. As a passive unit, it connects field wiring to I/O modules and includes a segment of the ModuleBus. Two mechanical keys—each with six positions—allow 36 different configurations to match various I/O module types, purely mechanical and not affecting functionality.
